青年单侧上肢远端肌萎缩症——肌活检及与运动神经元病的鉴别诊断

Juvenile distal muscular atrophy of unilateral upper extremity. Report of 28 muscle biopsies

对28例青年单侧上肢远端肌萎缩症,进行肌活检的组织病理、酶组织化学及电子显微镜检查。由于本病临床易误诊为运动神经元病,故选后者24例肌活检作对照研究。结论为肌活检可帮助两病的鉴别诊断。

Muscle biopsies in 28 cases of Juvenile distal muscular atrophy of unilateral upper extremity were studied by histopathology, enzyme histochenistry and ultrastructure. Because the disease were more frequently misdiagnosed as motor neuron disease. Contrast studies were done in 24 cases with MND. Results suggest that their differential diagnosis is possible by musice biopsy.
